Experimental investigation on the overall cooling effectiveness of t-type impinging-film cooling
Applied Thermal Engineering, 2018Abstract This paper presents an experimental investigation of impinging-film cooling concerning the effects of various factors on overall cooling effectiveness η. The factors include blowing ratio M (0.31 ≤ M ≤ 1.84), non-dimensional jet-to-plate pitch Zn/d (1 ≤ Zn/d ≤ 2), non-dimensional spacing of jet holes Yn/d (1.6 ≤ Yn/d ≤ 2.4) and diameter of ...

The Effects of Channel Supplies on Overall Film-Cooling Effectiveness
Volume 7A: Heat Transfer — Combustors; Film Cooling, 2023Abstract Cooling components in the hot section of a gas turbine is essential to component durability. Common methods of cooling include rib turbulators in internal passages and film cooling on external surfaces. The holes that produce the film cooling are fed from the internal channels often containing ribs.

Overall Cooling Effectiveness With Internal Serpentine Channels and Optimized Film Cooling Holes
Journal of Turbomachinery, 2023Abstract The overall cooling effectiveness for gas turbine airfoils is a function of the combined cooling due to internal cooling configurations and film cooling configurations. Typically, film cooling configurations are evaluated independent of the cooling effects of the internal feed channels, generally based on adiabatic effectiveness

Abstract The effects of geometrical parameters on overall cooling effectiveness were experimentally investigated on the flat plate with impingement/effusion cooling. Geometrical parameters investigated included two relative positions of impingement and effusion holes (staggered arrangement and overlapped arrangement) and three impingement gap ...

Abstract Increasing interest in the use of ceramic matrix composites (CMCs) for gas turbine engine hot gas path components requires a thorough examination of the thermal behavior one may expect of such components. Their highly anisotropic thermal conductivity is a substantial departure from traditional metallic components and can ...

Adiabatic and Overall Effectiveness for a Film Cooled Blade
Volume 2: Turbo Expo 2004, 2004Laboratory studies of film cooling performance for turbine section airfoils typically quantify adiabatic effectiveness and occasionally the heat transfer coefficient for the film cooling configuration. In this study the normalized airfoil metal surface temperatures are obtained directly by using a test model that has a material conductivity scaled to ...

The cooling system is required to ensure gas turbine can work at high temperature, which has exceeded the material limitation. An endwall cooling test rig was built up to conduct the endwall cooling research. A detailed work was done for analyzing characteristics of endwall heat transfer and discussing the multi-parameter influence mechanism of overall

Adiabatic and Overall Effectiveness for a Fully Cooled Turbine Vane
Volume 3B: Heat Transfer, 2013Adiabatic and overall effectiveness data were measured for a fully cooled, scaled up turbine vane model in a low speed linear cascade with a chord-exit Reynolds number of 700,000. The overall effectiveness is a measure of the external surface temperature relative to the mainstream temperature and the inlet coolant temperature, and consequently is a ...
